SASH-FASTEN ER.

SPECIFICATION forming' part of Letters Patent No. 540,082, dated May 28,1 895.

Application filed January 15,1894- Serial No. 496,921. (No model.)

To a/ZZ whom it may concern:

Be it known that I, JOSEPH D. WESTGATE,

of Boston, in the county of Suffolk and State of Massachusetts, haveinvented certain new and useful Improvements in Sash-Fasteners,

of which the following is a specification.

This invention relates to that kind or class of devices which areemployed to draw together the meeting railsof Window sashes to 1o shutout dampness and cold, and to look the sashes against being raised orlowered. y

It is the object of the invention to provide a sash fastener which maybe simple in, and economical of', construction, be readily and I5 easilymanipulated, and at the same time be efficient for the purpose for whichit is iutended in a maximum degree.

To these ends my invention consists of a sash fastener comprising initsconstruction, zo two base plates, secured one to each' of the meetingrails, a swinging lever pivoted on one base plate and having a caniprojection to engage a cam on the opposite plate, a spring pressed pinon said lever adapted to engage z5 two or more holes in the plates tohold the leverin locked and unlocked positions, means for automaticallybringing the lever to a locking position when the sashes are closed, andindependent means for positively securing 3o the lever in a lockedposition or releasing it therefrom, all of which I will now proceed todescribe and claim.

Reference is to be had to the annexed drawings and to the letters markedthereon, form- `ing a part of this specification, the same lettersdesignating the same parts or features, as the case may be, whereverthey occur.

Of the drawings, Figure l is a plan View of my improved sash-fastener,showing the parts 4o as in locked or closed position. Fig. 2 is asimilar view showing the fastening devices as in released position. Fig.3 is a front view of Fig. 2, showing the lower sash as slightly raised.Fig. 4 is a vertical sectional view of Fig. 3, taken on the line 4 4.Fig. 5 is a sec` tional detail View taken on the line 5 5 `of Fig. 4.Fig. 6 is a sectional detail view similar to Fig. 4, showing theposition of the parts at the moment of the complete closing of the 5otwo sashes. Figs. 7 and 8 are respectively a plan and a side View of asimplified form of the invention.

In the drawings, ct designates the lower and b the upper sash of awindow, and c, d are respectively their meeting rails.

e is a base plate secured to the lower rail c, and f a similar platesecured to the upper rail CZ.

Referring to Figs. 1 to G, inclusive, g is a swinging lever pivoted uponthe base pllatef, 6o and provided at one end with a vertically arrangedhollow handle in which is arranged a vertically movable springpressedpin. A spring-pressed piu h, having a head 1.' by which it may be raisedand lowered, and by which, in connection with the protecting tubejlsurrounding the spring lo, the lever g may be manipulated so as to swingit around on its pivot. The other end of the said lever is provided witha cam projection l, constructed 7c and arranged to engage the cam m onthe plate e, and so operate to draw the sashes together when thefastener is in closed position, as shown in Fig. 1. When the sashes arein the last mentioned position, the lower end of the pin h will beforced into a hole n in the plate e and hold the lever g againstmovement until rthe said pin is again raised by hand. Thus the lever issecured against being swung y to an unlocked position by the insertionof a 8o knife blade or other thin metallic strip between the sashes. Thepin, being provided with means c., an enlarged head) for lifting it, maybe raised by hand independently of the devices which are hereinafterdescribed. 8 5

o is a hole also formed in the base plate e into which the lower end ofthe pin h may be forced by its spring`when the fastening device is inunlocked position, as represented in Figs. 2 and 3. A spring p surroundsthe 9o pivot q of the swinging lever, and is so connected with thelatter and the base plate e or sash as to operate with a strong tendencyto move the said swinging lever to closed or latched position. i

r is a lever fulcrumed under the base plate c, and having a proj ectious on its upper face, directly beneath the pin h, as is best seen inFigs. 4, 5 and 6. The outer end of the lever fr projects slightly beyondthe inner edge of zoo the sash c, so that upon closing the sashes, withthe fastening devices in the -position in which they are shown in Figs.2, 3 and 4, the said projecting end of the said lever will be broughtinto engagement with the rear edge of the plate e, raising the lever r,lifting the pin h, and releasing the swinging lever g so that thespringp may operate to. snap it into latched position, as is representedin Fig. 1.

In Fig. 6 the parts are shown as on the point of operating as lastdescribed.

In Figs. 7 and 8 my improved fastening device is shown as designed to beoperated by hand only', the cam engaging end ot' the swinging lever gbeing in this case, (by preference though not necessarily) on the end ofsaid lever provided with the spring-pressed pin h.

The operation of the invention has been so fully set forth in thedescription of its construction as not to need further explanation.

I am aware of the fact that a sash fastener has been heretofore made orproposed having a lever journaled on an axis with an interposed spring,and a trip device to automati# cally throw the lever into its lockingposition, and I do not claim broadly'such a construction. In my fastenerI employ two plates, one of which is provided with a cam, there beingalso a recess in one of them, in combination with a pivoted lever whichis constructed with a cam engaging projection, and with a verticaltubular guide in which is mounted a spring pressed pin for entering thesaid hole, whereby the lever is held inits locking position. Byprovidingthe lever with the vertical tubular guide and spring pin, Ifurnish a comparatively large. handle, as it were, which can be graspedfor swinging the lever. The pin is provided with an enlarged headextending above the guide, so that it can be easily moved vertically.

Having thus explained the nature of theinvention and described a way ofconstructing and using the same, thoughwithout attempting to set forthall the formsin which it may be made, or all of the modes of its use,itis declared that what is claimed is y A sash fastener comprising in itsconstruction, two base plates, a swinging lever pivoted on one baseplate and provided with a cam projection to engage a cam on the oppositeplate, a spring pressed pin on said' lever adapted to engage two or moreholes in the plates to hold the saidlever in locked and unlockedposition, a lever fulcrumed under one of the base plates and adapted tobe engaged and operated when the sashes are closed to raise the springpressed pin when the lever is in an unlocked position, a springconnected with said lever and its base plate to operate with a tendencyto move the lever to a locked position, and means independent of saidpin lifting lever, for moving said pin so as to hold the swinging leverin a locked position or to release it therefrom, substantially as setforth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 11th day of January, A. D.1894.
